Hi guys, So I was set on buying the 45 for my candid street photography, but I've decided to sell my Canon gear and therefore have more money to play with and could afford/justify the 75. After reading the reviews, the 75 seems to be an all-around winner. However...is it a better lens for street photography? My main street/candid lenses have been the Canon 100 on full frame then the 135L on full frame. I like the distance the 135L affords, though sometimes I wished I could zoom out a bit...overall, I did prefer the 135mm FL, though...since I like to stand back and observe and not be observed. (Nothing creepy about it, I just don't want to bother my subjects). What's your take on it?
